A delicate California native perennial with narrow, grass-like foliage and small, bright blue flowers with yellow centers. It thrives in dry conditions and is excellent for rock gardens and native plantings.
Why grow it
Western blue-eyed grass offers a low-maintenance alternative to turf or bedding plants in dry, well-drained settings where many ornamentals struggle. Unlike some ornamental grasses, its fine texture and modest height (typically under 12 inches) make it suitable for rock gardens, borders, and water-wise landscapes without dominating neighboring plants. It provides early spring color and attracts pollinators while requiring minimal fertilizer or supplemental water once established.
Watch out for
Plants may decline in heavy clay or poorly drained soils despite drought tolerance in ideal conditions. In regions with summer humidity or frequent overhead watering, fungal issues can occur, so spacing and air circulation deserve attention. Seeds readily self-sow in favorable conditions, which some gardeners find useful for filling space but others may need to manage.
